GLP-1 injection site rotation: what the labels say, and a free planner

Ozempic, Wegovy, Mounjaro and Zepbound are all injected under the skin of the abdomen, thigh or upper arm, and all four labels say to rotate. Here is the exact wording, plus a planner you can print.

Quick answer

Inject under the skin of the abdomen, thigh or upper arm, and rotate the site. The Mounjaro and Zepbound labels say to rotate sites with each dose, and to have another person inject the back of the upper arm [1][2]. The Wegovy label also says to rotate with each dose [3]. The Ozempic label says to use a different injection site each week when injecting in the same body region [4]. None of the labels prescribe a specific rotation order, so the planner below is an example pattern, not a medical rule.

What each label says about injection sites

MedicineWhere it can be injectedRotation wordingNotes from the label
Mounjaro (tirzepatide)Abdomen, thigh, or back of the upper arm if another person injects [1]Rotate injection sites with each dose [1]With insulin: separate injections, same body region is acceptable but not adjacent [1]
Zepbound (tirzepatide)Abdomen, thigh, or back of the upper arm if another person injects [2]Rotate injection sites with each dose [2]Once weekly, any time of day, with or without meals [2]
Ozempic (semaglutide)Abdomen, thigh, or upper arm [4]Use a different injection site each week when injecting in the same body region [4]With insulin: same rule as above [4]
Wegovy (semaglutide)Abdomen, thigh, or upper arm [3]Rotate injection sites with each dose [3]Time of day and injection site can be changed without a dose change [3]
Wording from the US prescribing information, retrieved 6 October 2026. Your pen or vial has its own Instructions for Use, so follow those too.

The pattern is the same across all four: three body regions, and a different spot each time. The one real difference is the upper arm. For Mounjaro and Zepbound the label says another person should inject the back of the upper arm, which is hard to reach yourself [1][2].

Example pattern only. The labels say to rotate sites, not in what order. Follow your prescriber and the Instructions for Use.

The labels tell you to rotate but not in what order [2][4]. This planner simply cycles through your chosen regions and sides so that you never repeat a spot back to back. Nothing you enter is saved or sent anywhere.

Which medicine are you looking for?

  • Tirzepatide: see the Mounjaro and Zepbound pages for the exact label wording on each.
  • Semaglutide: see the Ozempic page. Wegovy follows the same three regions.
  • Missed an injection? The window differs by medicine, so see the missed dose guide.

Frequently asked questions

Where do you inject a GLP-1 medicine?

Under the skin (subcutaneously) of the abdomen, the thigh or the upper arm. For Mounjaro and Zepbound, the label says to inject the back of the upper arm only if another person does it. Rotate the site each time.

Do you have to rotate GLP-1 injection sites?

Yes, the labels tell you to. Mounjaro, Zepbound and Wegovy say to rotate sites with each dose. Ozempic says to use a different site each week when injecting in the same body region.

Is there an official injection site rotation chart?

The prescribing information does not publish a fixed order. It says to rotate. A chart or planner is a way to follow that instruction, not an official protocol.

Can I inject in the same body region every week?

The Ozempic label says to use a different injection site each week when injecting in the same body region, so the region can repeat but the exact spot should not. Ask your prescriber or pharmacist what they prefer.

Can I use the same area as my insulin?

The Mounjaro and Ozempic labels say it is acceptable to inject the medicine and insulin in the same body region, as separate injections, but they should not be adjacent to each other.
